Google Earth: Suspected Earth Impact Sites (KML)

NOTICE: The KML has been updated.

Impact IconA while ago I found the Impact Field Studies Group:

… The overall intent in forming IFSG is to bring together widely-separated researchers doing work at a variety of impact crater locations to share the observations and field experience for the common good of the impact community.

What’s most interesting about this group is that they’re maintaining a massive data base of 543 suspected Earth impact craters. Note the bold suspected! Now, you may know I’ve already converted the confirmed ‘Earth Impact Database’. You can imagine the former one just has Google Earth written all over it. So without further ado I present you:

All 499 Unconfirmed impact craters on earth,
Google Earth KML the SEIS Database in KML (144KB) (Mac users see note below!)

What’s in this database?
Well three times the dents you got from the confirmed one. Mostly small craters, but a few extremely large ones like the 800 km (~500 mile) Bangui in Africa (covering almost the entire Central African Republic). I had to skip a few because of lacking coordinates. Not all data is correct, as you may notice a few scattered in mid-ocean, just click the icon to find out where it should belong. It’s all a matter of garbage-in-garbage-out (apart from the few conversion mistakes made by me). I hope you’ll enjoy this one.

Note: no network link this time as I didn’t want to polute the confirmed database and fear my little server won’t handle the load churning up 499 craters. 🙂

IMPORTANT NOTE FOR MAC USERS: I found out yesterday that this KML collection borks Google Earth for Mac. Please do not save it in your ‘My Places’ folder as it will work fine at first but after a restart you may loose all your placemarks! Because of some weird character bug, where otherwise fine KML data gets corrupted, it brings down your entire collection. Don’t ask me why or how. You can leave it in your ‘Temporary Places’ folder, just remember NOT to save it.
If you did get the corrupted ‘My Places’ you can get your placemarks back by visiting your ‘~/Library/Application Settings/Google Earth/’ folder (or something like that). Your placemarks file resides there and you may salvage what’s left of it.
Sorry, GE for Mac’s really Beta I guess. 🙁
It works fine on GE for PC, though!

Update 2006-02-21: I think it’s now safe for Mac users, provided you’ve updated to the latest beta.

Olympic Imagery 2006

Torino 2006 identityThe Winter Olympics 2006 in Turin are going to break loose some time next week. In case you didn’t know. In any case I just found out about the new ‘identity’ of The Games. Poynter Online is running a small story about the visual identity: Knowing Your Audience: Lessons from Olympic Imagery

Where the story is going I don’t know. But you’ll probably see those graphics multiple times on television.

Google Code: Web Authoring Statistics

Over at Google Code they ran a survey, in December 2005, looking at a couple of webpages trying to find out which elements and their respective attributes are used most. And more importantly how they are used.

We took a sample of slightly over a billion documents, and looked at what elements were used on the most pages, what class names were used on the most pages, and so forth.

Pretty interesting read this Web Authoring Statistics study.
E.g. why would anyone use a <table>-tag and not put any <td> or <tr> inside? Beats me… Is it a remnant of MS ‘HTML’? Or someone deleting a table in a WYSIWYG environment? And there are more examples.

Which Browsers matter in 2006?

BrowsermixIf you are planning to build or rebuild a site this year you may wonder at some point which browsers you should support. If not, you should! Just looking at your new design in IE 6 is no guarantee it works and behaves the same in any other browser.

Not that long ago the browser shortlist consisted of IE 6, combined with IE 5, IE 4 & Netscape 4. And maybe some other occasional ‘weird’ browser. But times have changed and are changing. IE 4 & Netscape 4 are ancient history, support for IE 5 has been dropped in most cases by Microsoft itself. And there are emerging new browsers, either driven by innovation or security issues.

So what browsers should you support today and for the upcoming year(s)? Simple question, simple answer: Check your visitor stats and build/optimise for what they use.

RE: Adobe looking for a Gecko expert

Adobe, formerly Macromedia That is what the below job offering says. But I’m not quite sure what it is they’re building. Remember the Adobe & Macromedia merger? So it’s quite obvious that the the product lines of both will be merged. Meaning Flash and PDF …

WordPress 2.0 Cache Is Broken!

WordPress takes a bite. As of version 2.0 of WordPress you’ll get a caching feature, which means it’ll ‘remember’ the most frequent accessed static information from your blog. This way it’s supposed to not bother the database but make a ‘fast trip’ to the server to fetch these pieces of info. In the end this should make your weblog go faster, because the information is already there to present.

Unfortunately it’s broken. Continue reading “WordPress 2.0 Cache Is Broken!”

Google Earth for Mac, download now

Google Earth (no longer beta)It’s official! Google Earth for the Mac is here. While Google Earth for the PC was stripped off its beta status, they’ve also released the Mac version. You’ll need OS X 10.4 and up (see the requirements).

Get Google Earth for Mac (or PC)

Read the official anouncement and Stefan from Ogle Earth already has a review up.

Is it too soon to be asking for a ‘Pack for Mac‘? 😉

Is WordPress 2.0 that sluggish?

ThinkLemon in AlphaDirectly after upgrading this weblog, little over a week ago, I felt it was a little bit sluggish. Compared to the 1.5 version I was running before. Maybe it could be just the webserver as I’m running on a shared hosting solution. Therefore one of the neighbours could be having a party… again. 🙁

But finding it slow on and off I decided to see how slow or fast WordPress 2.0 really is. This new incarnation of everyone’s favorite weblog tool supports ‘object caching’. Caching generally is a good thing. The results? Hmmm not good…

Learning 101 – IKEA style

Don’t ask me how I got subscribed to Will’s Weblogg-ed. But reading today’s post on ‘Learning 101‘ leaves me with an ‘IKEA‘-feel to it. Especially:

  • Use visuals!
  • Use the filmaker (and novelist) principle of SHOW-don’t-TELL.
  • Use “chunking” to reduce cognitive overhead.
  • Don’t rob the learner of the opportunity to think!
  • Context matters.

To name a few. This makes you wonder why so many people are still figuring out how they will ever finish their newly bought ‘Billy‘… Hold on:

  • Emotion matters!
  • Since stress/anxiety can reduce focus and memory, do everything possible to make the learner feel relaxed and confident.

Maybe it’s time to replace the paper instructions with something else… *Surpressing the how-to-bolt-together-your-IKEA-furniture.blogspot.com-thought* *REAL HARD*
